Can an answer for 9b have

the bunsen burner varies in temperature therefore it is hard to keep a constant temperature and have a good separation of mixtures.

I said that the alkanols were combustible, but now i think i'm wrong. uh oh.

Any chance of 40 with high A/low A+? what would be required end of year?

I got an A/A+ on the two chem exams (with A+ for coursework). My midyear A was one mark off the A+ cutoff and my end of year A+ was very high, can't remember the exact mark. I got a 44.xx scaled. So I would say, yes, you can still get 40.

35/36?

You have given me hope
Haven't been around the VCE system for a while now, but with a very strong end of year mark you could do it. (that's only my opinion though, someone else more familiar could give a better estimate)

[bubsy]

Meh, atm I concede 2 marks. I'm just praying that I filled out the MC answer sheet right.

I also pray that a bug crawls into my paper and takes a shit on page 21, right in between the 1 and the 5 so it looks like there is a decimal point and reads 1.5 L haha...

I did the same thing - I used the density formula and didn't realise that it was in mL, not L

for 7 b ii i put C21H31COOH is that still correct?

[Blakhitman]

Should be correct.

[98.40_for_sure]

omfg... i put C23H34O2
didnt pick up that the 22 carbons included the C from COOH fml

[98.40_for_sure]

hmm do you think its possible to still get 40 raw if im averaging A in school work, and around 60/75 for this exam?

[brendanbob]

so i freaked and paniced during the exam, thought it was too easy and kept on second guessing myself, and that has led to the wrong answer ... acoording to mao's answers i think i probably 47/75, but im hoping for a study score of 33/34, do you think that it is still possible or would i be looking at an underaverage score below 30?

Question 9C).....
if i forgot to mention hydrogen bonding in regards to propan-1-ol but mentioned its polarity and dipole dipole bonds and that butane is non polar and has dispersion forces i might get the 3 marks? :S

[Streaker]

Hey if I get two C+'s for my exams and like an A or B+ for coursework, is there still any chance I could pull a 30 raw in chem?

[physics]

is it alright for the ratio question for biodeisal to put 3/1 instead of 3 D:
and i think i wrote butane was polar by accident but i metioned the foorces and stuff so i should still get like 2 or 1 malrks out of 3 D: right right?

[Sunny10]

well feck me

[crayolé]

Anna, i wrote 3:1 :L

[Studyinghard]

What is wrong with 3:1 . that is the answer isnt it? it asked for ratio. so you cant just write 3. infact 3 would almost be wrong.

[Blakhitman]

Technically if you write:



would you get the mark?
